SPECIFICATION forming part of Letters Patent No. 300,740, dated June 17, 1884. Application filed April 5, 1884. (No model.)

To all whom t may concern,.-

Be it known Athat I, MORRIS S. SHIPLEY, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Pencil- Holders, of which the followingis a specification.

My invention relates to an improvement in v lead-pencils.. It is also adapted to be used in my improvement.

connection with pens, tooth-picks, and other lsimilar articles.

The object of my invention is to provide a novel construction and combination of devices for-inserting and withdrawing the lead by the turning` of the barrel of the pencil, which may be also turned far enough to automatically eject the lead by means of a plunger, which will automatically be reset in position to receive the lead when the barrel of the pencil is turned in the opposite direction, all of which will be fully set forth in the description of the accompanying` drawings, in which- Figure 1 is a longitudinal vertical section of Fig. 2 is a plan view of the lead-holder. Fig. 3 is a section on line x x, Fig. 2. Fig. 4 is a plan view of the spiral screw. Fig. 5 isa plan View of the slotted tube. Fig. 6 is a broken sectional elevation, showing the parts in the position occupied at time of ejecting the lead.

A represents the barrel of the pencil.

B represents a point, made of metal or other suitable material, upon which the barrel Ais j ournaled or swiveled in the ordinary manner.

C represents the lead holding and carrying tube, preferably constructed of an outer shell, within which is inserted a secondary shell, c, which is spun or flared so that the lead may be easily inserted. This inner shell, c, also acts as a seat for a spiral spring, e. Itis coiled d represents a' guide pin on the plunger that projects up through a slot, b, formed in the tube C. The guide-pin d is diamondshaped, so as to iit the screw-slot, to fur.

nish increased wearing -surface and prevent lost motion. This diamond-shaped pin is applicable to be used in all devices where the advancing or retracting of the point is ac-v complished by the combination of the spirallyslotted tube and the straight-slotted tube- .such as tooth-picks, pen-holders, die.

E represents a spirally-slotted tube or worm, which is placed concentrically Within the barrel of the pencil A, as shown .in Fig. l.

F represents a straightslotted tube, in which slides the leadholder or carrier C. It is secured at the forward end to the metallic point B, which holds it fixed concentrically within the spiral tube E. The pin d projects up through the slot hin tube F a sufficient distance to work in the spiral slot or worm Z, formed in the worm-tube E, which is secured to the barrel A, so as to revolve with it in any desired manner. I have shown it as attached by means of a collar, G. The parts are secured together as shown in Fig. l. plunger D is held retracted, as shown in Fig. 3, by the tension of the spring e, so that the lead may be inserted within the holder C and rest upon the end of the plunger D. When the barrel A, carrying with it the worm E, is revolved, the pin d moves through slot Z and carries the holder tube C forward when the barrel is turned, say, to the right. This motion is continued until the point of the leadtube C is projected against the inward flaring mouth fr' of the point B, which arrests the motion of the lead-tube C.- If it is desired to eject the lead, the barrel A should be turned farther, when the pin d will be forced forward in the slot b, forcing the plunger D forward within the tube C, compressing the spring e until the lead H is ejected, as shown in Fig. 6. The movement of the barrel A is then reversed, which allows the recoil of the spring in the retraction of the plunger D within the carrier-tube C to its normal position, and the carrier-tube is withdrawn by the continued revolution of the barrel in the same direction. A new lead may be inserted as soon as the barrel A is turned back a sufficient distance to retract the plunger to its normal position shown in Fig. 3.

AInstead of having the tube C composed of two pieces of metal, it may be made of a single piece, and a washer secured within the same, to form aseat for the spring c; but it is cheaper and casier made of two pieces, as here shown.

The constructing of the regulating devices vfor moving the lead-carrier and operating the plunger by the use of longitudinal slots is superior to the devices hitherto employed for The IOO

, no space for the insertion of the lead.

By the introduction of the spring devices in connection with the straight slot in the carrier the carrier is held in its normal position for the insertion of the lead at all times, the plunger being automatically retracted for its reception.

A pencil has heretofore been composed of a barrel, a spirally-slotted tube, alon gitudinallyslotted tube, `a lead-carrier, and a lead-ejecting plunger operated by a pin, and acted on by a coiled spring to permit a yielding movement of the plunger when it is forced forward against the spring to eject the lead. Such features, therefore, I do not broadly claim; but

The combination of the lead-carrying tube C, having the longitudinal slot I), closed at its ends, the plunger D, inclosed within the carrying-tube, and having a guide apin, d, projecting through and moving in the slot in said tube, and a spring, e, on the plunger, inside of the carrying tube, with the longitudinally slotted tube F, the spirally-slotted tube E, and the barrel A, as shown and described.

In testimony whereof I have hereunto set my hand.

MORRIS S. SHIPLEY.
